Application of TRIZ innovative method in the numerical control processing of plastic plates

Aiming at the sticking problem of plastic plates in CNC machining, an innovative solution based on TRIZ theory is proposed. On the basis of analyzing the interaction, function, and causal chain of components such as spindle, tool, plastic plate, cutting, nozzle and compressed air in the CNC machining process, find the root cause of the sticking problem, and then use contradiction analysis and object-field model The analysis puts forward the solution of adding a fan on the main shaft and replacing the gas nozzle with a water mist nozzle. After application verification, this method effectively reduces the sticking phenomenon of plastic plates in processing and improves the processing efficiency.
